Committee invited to on-site tour as sewer district plans major Lower Lake dam work

John Barber, a member of the Climate and Environmental Sustainability Committee, invited committee members and city council to a site tour of Lower Lake and the dam area, saying the Northeast Ohio Regional Sewer District (NEORSD) plans major reconstruction work that could occur in 2027–2028.

The Friends of Lower Lake, which Barber said has been doing stewardship work at the site for eight years, will offer hour-long walking tours from Lovers Lane on Brook Road so elected officials and staff can see proposed changes and hear engineers’ and stewards’ perspectives. “What the sewer district is talking about is the concrete. It's all about the concrete and the walls and the volume of water,” Barber said, adding the Friends will highlight the site’s human and natural history.

Why it matters: the project affects property lines and public access across municipalities. Lower Lake sits near the border of Cleveland, Shaker Heights and Cleveland Heights, and Barber and other speakers said proposals to raise flood walls or remove the existing earthen dam from 1836 could change the appearance and use of the lake and nearby parkland and affect Coventry Road and the North Park–Coventry intersection.

Committee members described several engineering and ecological trade-offs discussed at the meeting. Barber said the Ohio Department of Natural Resources (ODNR) regards the existing earthen dam as failing, and that ODNR requires either repair or removal; he quoted the agency as saying the dam “has to be fixed or removed.” He also described NEORSD’s current design emphasis on hard engineering: “the flood wall … is pretty massive, and it's really gonna change the whole dynamic,” member Jim Posch said during the discussion.

Committee members and volunteers noted several specific impacts and constraints mentioned at the meeting: Brook Road would be removed along the dam, parking on the dam would be eliminated, and vegetation on the lake side would be limited to species no higher than about 6 inches to prevent burrowing animals from undermining an earthen structure. Barber said the sewer district’s diagrams propose a flood wall intended to protect the North Park–Coventry intersection, which he said typically fills and is blocked for four to five days when the lake floods.

Speakers also raised questions about replacement planting and canopy loss: Barber said the plan calls for replanting but warned that “you plant a 15-foot tree, it does not replace the ecological services of a 50- or 60-foot tree.” He noted that many trees immediately behind the dam are short-stature species (dogwoods, crabapples) while older canopy trees in adjacent historic gardens would not be removed.

On process, committee members asked that cities and residents be engaged early in design. Barber and others urged NEORSD and the cities to include landscape and nature-based solutions alongside the engineering design, noting that engineers have prioritized hardscape and that earlier public involvement would preserve design options. The Friends of Lower Lake and the committee will coordinate dates (Barber proposed April for initial dates) and will use a poll to schedule weekday and weekend tour options; the tours are free, Barber said.

The committee did not take formal votes on the project at the meeting. Speakers said NEORSD will present design materials to the cities before construction and will likely request funding for amenities, as it did for the Horseshoe Marsh project. The Friends of Lower Lake and committee members plan to bring comments from the tours back to council and staff for use during review and funding discussions.

What’s next: Friends of Lower Lake will circulate a scheduling poll to council and city staff. NEORSD’s design and ODNR’s requirements will determine the final scope and timing of work, and the committee said it expects additional opportunities for review once NEORSD issues designs and funding requests.
